Path finding on a 2d plataformer game. Making enemies jump - unity3d

I am working 2D Platform running game and I am stuck at this issue, i cant figure it out how to make my enemies jump through platforms as they follow the player. I used A* path finding with a Grid graph for my flying enemy and it works just fine. But with the ground troops i don't know what to do. Any recommendations where to start and what to study? Thanks in advance

Place a Trigger (Collider) attached with the Platform at the point where you want your enemy to Act (Jump in your case). and Attach a script to your Enemy to Handle its actions whenever it enters that trigger. you can make it Jump/Fly or whatever you want to. Thumb up if its helpful :)

using unity physics with SteamVR

I want to make a plank game in VR with Unity. So when the player walk outside of the plank, he falls. Right now the only way to make it work is by using VRTK which is another physics system and it makes a lot of things complicated.
I've put a rigidbody on the CameraRig and uncheck "is kinematic". The player falls, but the colliders on other objects are not working anymore...
Is there a way to use Unity's physics with SteamVR and without VRTK ??
Thank you !
Firstly I would read up on Rigidbodies and Colliders/Trigger Colliders - here's a link.
Here's a useful table from that website:
You will need to use this to understand why the player is falling. Is the CameraRig actually colliding with the ground? Is it a Trigger Collider (which has a callback method but doesn't do any physical collision). There's many possibilities for why.
I wrote a script that you can drag in two objects and see if they collide. You could use that if it helps.
The issue in VR with Vive is that determining where someone walks can be difficult, as we are only tracking their head and their hands. If you have a Vive Tracker available and it fits your use case you could use that to track someones foot.
What I have done in the past is use the Camera(eyes) GameObject within the CameraRig and get it's transform.position.x and transform.position.z value to determine if it has gone outside of the boundaries of the object the user is standing on.
Hope this helps,

How to detect which block is closest to player? (Unity3D)

I am making a game simlar to MotherLoad. I'm trying to figure out how to mine downward. I've tried using OnCollisionStay and mining towards the block that the player is colliding with, but normally the player is on 2 blocks at once, so that isn't working.
Does anyone know a better method to do this?

unity3d player gameobject "hear" sounds

I have a question that is a little... complex
basically I want a gameObject (an enemy) "listen" to the sound of the player (footsteps, door opening, gunfire etc)
I could do this just fine by using:
>Collider[] hitColliders;
>hitColliders = Physics.OverlapSphere(transform.position, 10f,enemyLayer);
>
>for(int i=0;i<hitcolliders.Length;i++){}// Call Enemy Hear Player Function
However, the problem starts here:
I want the "sound" to be blocked by walls. At first, I thought I could use Physics.Linecast to do this. However, this means the sound could be blocked by a mere piece of pole, because Physics.Linecast only shoots a single, straight line.
What I want is player C could not hear anyone at all, but player A and B could still hear each other.
I hope you guys understand my question.
You could place the objects you want to block the soundwave on a specific layer. And just make the raycast ignore all other layers.
Leave all this Physic and other graphical stuff behind.
Create a separate logic for this behavior.
Create a big chess board (where x,y will be x,y position in you game) and add only sound-generators, sound-listeners and sound-obstacles.
Update this chess board each frame and create sounds, fly sounds, block sounds and listen to sounds and act appropriate as the real life actors.
This way you can add parameters to each obstacle, sound-generator and sound-listener so that all be configurable.

How to change the shooting accuracy?

I am making an FPS game using unity 3d, I've a problem in the shooting accuracy script. Can you tell me how I can change it with a single script that shoot the bullet and include the shooting accuracy and equipped to the gun, please?
If you are currently using a raycast, you should have no problem.
If you are spawning a sphere and thrusting it forwards, I suggest you use a raycast.
Raycasts go in a completely straight line. Bullets follow gravity, and quickly fall to the ground.
You don't see bullets, they move too fast. Raycasts are invisible.
When it hits something, it sends you back the information you need. If you make the sphere go too fast, it might glitch through objects.
You can learn about raycasts here.

Unity help, indie horror game

I am making a game using a combination of Blender and Unity and have hit a wall. I am trying to make it so a lamp flies off of a table and smashes against a wall once the player walks past a certain point in the map.
I am having a hard time with this. Any help is appreciated.
You need to break this up into little parts.
The first part is that once the player walks past a certain point you want to do something. To do this, look at http://docs.unity3d.com/ScriptReference/Collider.OnTriggerEnter.html
An on trigger event will let you run some code when an object collides with another object. In your case, when your player collides with a certain point in the game.
Next, inside that OnTriggerEvent, you want to fire the lamp off the table. To best do this, create a keyframe animation (or whatever you're most comfortable with) that animates the lamp to fly off the table. Lastly, play that animation in the trigger event. http://unity3d.com/learn/tutorials/modules/beginner/animation
To summarize, when the user hits a certain point, play an animation on the lamp.
